Custom data types

[wendy-aw]

• Modify generate_postgres_schema to return custom data types and their enum labels.
• Added get_postgres_triggers and get_postgres_functions methods to retrieve custom functions and triggers.

Thank you! Super neat implementation.

Replicated this by creating a copy of our private page_attributes.sql table in my local database.

Then, tested it with the python script below

from defog import Defog

defog = Defog("123", "postgres", db_creds={
  "host": "localhost",
  "port": 5432,
  "user": "postgres",
  "password": "postgres",
  "database": "postgres"
}) # api_key doesn't matter here

defog.generate_db_schema(
  tables=["page_attributes"],
  upload=False,
  scan=False
)

Can confirm that it correct gave us the custom_type_labels back for columns that had ENUM values.

Can also confirm that defog.get_postgres_functions() and defog.get_postgres_triggers() worked as expected.

Will publish this to pypi, update the version to 0.66, and then merge the PR!
